Other claims from this paper (9)
- Observation The main fraction was termed Lilium davidii polysaccharide.
- Observation LDP was an amorphous powder.
- Observation LDP contained D-mannose, D-glucose and D-galactose in an approximate 10 : 19 : 1 molar ratio.
- Observation At low solution concentration, LDP appeared as irregular crumbs or islands.
- Observation At high concentration LDP molecules formed an entangled rugged sugar layer.
- Observation LDP molecular weight was 5.17 x 10(4) g mol(-1).
- Observation The proposed LDP main chain comprises 1,4-linked beta-Glc and 1,3-linked alpha-Man at a 2 : 1 ratio.
- Observation On average one substituted alpha-Gal or alpha-Man residue occurred among 30 sugar residues.
- Observation The LDP reducing terminus was beta-Glc.
